A door that will not close without a shove, catches on the frame every time you pull it shut, or has developed a visible sag at the corner is one of the most common repair problems in UK homes. It is also one of the most misdiagnosed. Most people assume the door just needs planing. In most cases, that assumption leads to a door that still does not hang right, a gap that looks wrong, and a problem that comes back within months.
The reason is straightforward: a sticking or dropping door is a symptom. The cause is almost always something else entirely, and getting to that cause before you touch the door itself is what separates a lasting fix from a temporary one.
Why Door Problems Are More Common in UK Homes Than People Realise
British housing stock is old. A significant proportion of homes in the UK were built before 1960, and many still have their original timber door frames, joinery, and in some cases their original internal doors. Timber moves. It responds to temperature, humidity, and seasonal change in ways that more modern materials do not. It also settles, shifts, and gradually changes shape over decades of use.
Add to that the fact that most doors are repainted rather than stripped back between decorations, and you end up with hinges buried under layers of paint, frames touched up rather than properly maintained, and fixings that have never been checked since the house was built. A door that starts to stick at forty or fifty years old is not necessarily a sign of something seriously wrong. It is often just accumulated minor neglect catching up all at once.
The important thing is knowing which type of problem you are dealing with before you pick up a plane or a screwdriver.
The Most Common Reasons a Door Starts to Stick or Drop
Dropped or Loose Hinges
This is the single most common cause of a door that appears to have dropped in the frame. Hinges are fixed to both the door and the frame with screws, and those screws sit in timber that can dry out, compress, or be damaged over time. When screws lose their grip, the hinge plate pulls away fractionally from the timber. That small movement at the hinge is amplified at the opposite corner of the door, which is why the latch-side bottom corner tends to drop and catch on the floor or threshold.
In older properties, the hinge screws may simply have worked loose over decades of use. In other cases, the timber around the screw holes has compressed or crumbled, particularly if moisture has got in at any point, and the screws no longer have anything solid to bite into.
Timber Swelling Due to Moisture or Seasonal Movement
Timber absorbs and releases moisture from the surrounding air. In warm, humid conditions, particularly during a wet UK summer, internal and external doors can swell enough to start catching on their frames even if they hung perfectly all winter. This seasonal sticking is extremely common and tends to affect the top edge or the latch edge of the door first.
The frustrating thing about seasonal swelling is that the door often eases back on its own as temperatures drop and the timber dries out. This leads many homeowners to ignore the problem until it repeats the following year and the repeated swelling and drying begins to damage the frame or distort the door itself.
A Shifted or Settled Door Frame
Frames move. In older properties, the movement of the building over time, whether through ground settlement, changes in loading, or simply the long-term behaviour of the structure, can cause a door frame to shift slightly out of square. When a frame is no longer truly vertical or rectangular, the door that fitted perfectly within it starts to catch because the geometry has changed.
This is a more involved problem to correct than a loose hinge. It typically requires the frame to be assessed and, in some cases, adjusted or re-fixed before the door can hang properly again. Planing the door in response to a shifted frame is a common mistake: it removes timber from the door based on a frame that is itself incorrect, and the result is a door that fits the distorted frame only for as long as the frame stays in that position.
Paint Build-Up Over Years of Redecorating
Every coat of paint on a door and its frame adds a small amount of thickness. Over the lifetime of a house with multiple owners and multiple redecoration cycles, that thickness can become significant, particularly around the latch edge and the top of the door where clearances are tight. A door that cleared its frame perfectly when last hung may start to bind simply because it has been painted three or four times since.
This is one of the more straightforward causes to resolve but it is still worth identifying correctly. If paint build-up is the only cause, careful stripping and sanding can solve the problem without any re-hanging. If it is combined with a dropped hinge or a frame issue, addressing the paint alone will not be enough.
Structural Movement in the Building
Less common but worth being aware of: a door that sticks or drops suddenly, particularly alongside new cracks appearing at the corners of door or window openings, can indicate more significant structural movement in the building. If you have a door that has recently developed a problem alongside visible cracking in the walls or around the frame, get a professional to look at it before carrying out any repairs.

How to Tell What Is Actually Causing Your Door Problem
Before calling anyone or attempting any work, spend a few minutes looking carefully at the door and noting what you observe. The location of the problem tells you a great deal about its cause.
Where is the door catching? If it is catching at the bottom corner on the latch side, the door has most likely dropped, pointing to a hinge problem. If it catches along the top edge of the latch side, seasonal swelling or frame movement is more likely. If it rubs along the full latch edge, paint build-up or significant swelling is probably responsible.
Does the problem change with the weather or the season? A door that sticks in summer and eases in winter is almost certainly responding to moisture and temperature. One that sticks consistently regardless of the season is more likely to have a structural cause: a dropped hinge, a shifted frame, or a physical obstruction.
Has the door visibly dropped in the frame? Stand back and look at the gap between the door and the frame on all four sides. A well-hung door should have a consistent gap of around two to three millimetres on each side. If the gap at the hinge-side top is noticeably wider than at the bottom, or if the latch-side bottom corner appears lower than it was, the door has dropped.
Does the frame itself look square? A door frame that has moved will often show a visible lean or twist if you look carefully along it. Run your eye along the top of the frame from one side to the other. A spirit level placed against the hinge side of the frame will confirm this quickly.
Why Planing a Door Is Usually the Wrong First Move
The instinct when a door sticks is to remove material from the edge that is catching. This makes intuitive sense. But planing a door without first understanding why it is sticking is one of the most reliable ways to create a worse problem.
If the door has dropped because of a loose hinge, planing the bottom corner does nothing to address the hinge. The door will continue to drop as the hinge pulls further away, and you will eventually have a door with a noticeable bevel cut into the bottom corner and still no clean closure. If the frame has shifted, planing the door to fit a distorted frame means the door only fits correctly in that one distorted position. If the frame is ever corrected, the door will no longer fit.
Planing is sometimes the right answer, but it should always be the last step after the underlying cause has been identified and dealt with, not the first response to a door that is giving trouble.
What a Proper Door Repair Actually Involves
Hinge Adjustment and Re-Fixing
If the problem is a dropped or loose hinge, the correct fix is to re-fix the hinge properly. In many cases this means removing the hinge plate, filling the existing screw holes with either a proprietary filler or hardwood dowels, and re-fixing with new, longer screws into solid timber. Simply tightening the existing screws into stripped holes will not hold. For a door that has dropped significantly, it is also worth checking the condition of both hinges before assuming the problem is only in one of them.
Frame Realignment
If the frame has moved, this needs to be assessed carefully before any work on the door itself. Depending on the extent of the movement, the frame may need to be re-fixed to the surrounding masonry or timber structure, or in some cases replaced. This is work that needs to be done correctly because a door frame that is re-fixed without addressing the cause of its movement will shift again.
Careful Planing Where Genuinely Needed
Once the underlying cause has been dealt with, and if the door still does not hang freely, careful planing along the sticking edge may be appropriate. This should be done gradually, checking the fit frequently, and should always be followed by sealing the exposed timber with paint or oil to prevent moisture ingress at the bare edge. An unsealed planed edge is an invitation for the swelling problem to return.
Re-Hanging a Door From Scratch
If the door has been planed badly in the past, if the hinge recesses are damaged, or if the door itself has warped significantly, the cleanest solution is sometimes to re-hang the door properly from the beginning. This involves removing the existing door, assessing the frame condition, preparing the hinge recesses correctly, and hanging the door so that it sits square in the frame with consistent clearances on all sides. Where the frame itself needs attention, this can be addressed as part of the same visit through our carpentry repairs service.
When a Sticking Door Points to Something More Serious
The vast majority of sticking and dropping doors in UK homes are caused by the issues described above: hinges, swelling, frame movement, and paint. None of these are structurally serious, and all of them are fixable.
There are situations, however, where a door problem is a signal worth paying attention to. If a door that previously hung well suddenly develops a problem over a short period, and you can see diagonal cracking appearing at the corners of door or window openings in the same area, it is worth getting a professional to assess the building rather than simply repairing the door. Diagonal cracking at openings is one of the recognised indicators of differential settlement or structural movement.
This does not mean subsidence. Most settlement in UK properties is gradual and not serious. But it does mean the repair to the door should wait until someone with experience has looked at the bigger picture. A good tradesperson will tell you clearly if what they are looking at warrants further investigation rather than simply proceeding with the door repair.

Why DIY Door Fixes Often Make Things Worse
Door repairs are one of the most common call-outs after a homeowner has attempted a fix themselves. The pattern is almost always the same: the door was sticking, material was removed from the wrong edge, the underlying cause was not addressed, the problem continued or worsened, and now the door has both the original problem and an additional cosmetic issue caused by the attempted repair.
Doors are precision joinery. The gap between a well-hung door and its frame is measured in millimetres. Getting it right requires the right tools, an accurate read of the cause, and the experience to know how much material to remove and where. It also requires the finished work to be sealed and protected, which most DIY repairs skip entirely.
There is nothing wrong with attempting a minor adjustment on a door that is only just beginning to stick. But if the problem has been getting worse for more than one season, or if the door has visibly dropped in the frame, it is worth having it looked at properly before more damage accumulates.
What to Expect From a Professional Door Hanging or Repair Job
A proper door repair visit starts with an assessment. Rather than going straight to work, an experienced tradesperson will look at where the door is catching, check the hinge condition, assess the frame for squareness, and identify the root cause before deciding on the right approach.
Most door repairs are completed in a single visit. If the job is straightforward, such as re-fixing a dropped hinge or easing a seasonal swell, the work is typically done within an hour or two. More involved work, such as full re-hanging or frame adjustment, takes longer but is still usually a one-visit job. If you have other repairs that need attention in the same property, it is worth grouping them together into a single general maintenance visit rather than booking separate call-outs for each one.
You can read more about how we approach jobs and what to expect from a visit on the About page. If you have questions before booking, the FAQs page covers common queries about the process, pricing, and what to have ready.
Is It Time to Call Someone In?
If your door has been getting progressively worse, has dropped visibly in the frame, or has already been planed once without a lasting improvement, the sensible move is to have it assessed and fixed properly rather than continuing to work around it. A door that catches repeatedly eventually damages the frame, the threshold, or the surrounding plaster, and those repairs cost more than the original job would have.
We cover door hanging and carpentry repairs across North London, Hertfordshire, and surrounding areas. If you have a door that needs attention, or a list of jobs that have been building up alongside it, get in touch via our contact page and we will come back to you quickly with a straight answer on what needs doing and what it will cost.
